The teaching in one sentence
Diligence applied to skillful qualities — appamādo kusalesu dhammesu — is named as the single thing that, when developed and cultivated, secures benefit equally in this present life and in lives to come.
One of a cluster of “one thing” teachings
This discourse belongs to a recognizable pattern running through much of the Book of the Ones: a short list of near-identical openings — “this one thing, when developed and cultivated…”, “for an individual who transgresses in one thing…” — each isolating a single factor and following it through to a stated consequence. It is worth being honest about the shape of these texts rather than dressing them up as narratives they are not: there is no setting, no audience beyond “mendicants,” and no dialogue. The entire teaching is the claim itself, stated once in prose and once in verse.
Two ledgers, one entry
The distinction the discourse assumes — benefit “in this very life” (diṭṭhadhammika) against benefit “in lives to come” (samparāyika) — recurs constantly across the early texts as a basic frame for evaluating whether an action is worthwhile: does it help now, does it help later, or (ideally) both? Many actions satisfy only one side of that ledger. Wealth pursued carelessly might serve the present and cost the future; austerity pursued to excess might serve a future ideal while damaging present well-being. This discourse’s claim is unusually strong: one quality, diligence, secures both at once, without needing to be traded off against the other.
Not diligence in general, but in skillful qualities specifically
The text is precise about what diligence is applied to: not diligence as raw effort or industriousness in any direction, but appamādo kusalesu dhammesu — diligence specifically in skillful, wholesome qualities. Effort alone is not the point; effort aimed at what is actually beneficial is. This same term, appamāda, carries unusual weight elsewhere in the canon: it is the very word the Buddha is remembered to have used in his last recorded exhortation, “conditions fall apart — persist with diligence,” suggesting the tradition regarded this single quality as something close to a summary of the entire practice.
The verse’s closing move: astuteness as understanding, not just effort
The verse restates the prose claim, then adds a small but telling final line: the one who secures both benefits does so through “comprehending the meaning” — and it is this comprehension, not diligence alone, that earns the title paṇḍita, astute or wise. Diligence and understanding are presented as working together: diligence supplies the sustained application, and grasping the meaning of that application is what makes the person praised as wise rather than merely busy.

§1This was said by the Buddha, the Perfected One: that is what I heard.
§2“This one thing, mendicants, when developed and cultivated, secures equal benefits for both this life and lives to come. What one thing? Diligence in skillful qualities. This is the one thing that, when developed and cultivated, secures equal benefits for both this life and lives to come.”
The Buddha spoke this matter. On this it is said:
§3“The astute praise diligence
in making merit.
Being diligent, an astute person
secures both benefits:
§4the benefit in this life,
and in lives to come.
Attentive, comprehending the meaning,
they are said to be astute.”
§5This too is a matter that was spoken by the Blessed One: that is what I heard.
